How trade can help end plastic pollution
As plastic waste continues to choke oceans and overwhelm landfills, world leaders are turning to an unlikely but powerful solution: trade policy. The ongoing negotiations for a Global Plastics Treaty may mark the first time that international trade rules are used to confront the root causes of the plastic crisis. By redefining how plastic moves across borders and is produced in the first place, policymakers can transform global commerce into a force for circularity—where materials are reused, recycled, and kept out of the environment.
For decades, the global plastic trade has been built on an imbalance. Wealthier nations in the Global North exported massive quantities of plastic waste to developing countries in the Global South under the label of “recycling.” In reality, much of this waste was contaminated, mixed, or impossible to process. Countries like Malaysia, Indonesia, and the Philippines became dumping grounds for foreign refuse, often with devastating effects on their communities and ecosystems. Lacking the infrastructure to handle the influx, these nations saw rising levels of illegal dumping and open burning, releasing toxic fumes and sending rivers of plastic into the sea. The practice, often called “waste colonialism,” allowed richer countries to claim progress on recycling while offloading the environmental costs elsewhere.
The tide began to turn in 2019 with new amendments to the Basel Convention—the international treaty that regulates the movement of hazardous and other wastes between nations. The updated rules recognized certain types of plastic waste as hazardous and required exporters to obtain informed consent from the receiving country before shipment. In effect, the Basel amendments used trade policy to advance environmental protection, closing loopholes that once allowed contaminated plastics to flow freely across borders. Though enforcement remains uneven, the policy marked a turning point, signaling that trade can be used not just to facilitate commerce, but to curb environmental harm.
Now, the challenge is to extend that same principle to the entire plastic economy. If well-designed, global trade rules could accelerate a circular economy—one in which materials stay in use for as long as possible. Trade agreements, both bilateral and under the World Trade Organization, could remove tariffs on green technologies such as advanced recycling machinery, biodegradable materials, or recycled plastic feedstock. Lowering these trade barriers would make it cheaper and easier for companies to adopt sustainable practices across borders.
At the same time, harmonizing global standards is essential. Without consistency in how plastics are made, labeled, and recycled, even the most advanced recycling systems struggle to function efficiently. Trade policy can help align these standards by requiring that products traded internationally meet certain design criteria—such as being fully recyclable or containing a minimum percentage of recycled content. This kind of coordination would create larger, more predictable markets for circular goods, encouraging companies to invest in sustainable production and packaging.
Another key tool is Extended Producer Responsibility, or EPR. Under EPR systems, producers are held accountable for the waste generated by their products. Through trade agreements, countries could require importers and exporters alike to finance the collection, recycling, or safe disposal of the products they sell abroad. This would ensure that responsibility for plastic waste does not end at the border, but follows the product throughout its lifecycle.
Still, experts warn that recycling and circularity alone will not solve the problem. The sheer volume of new plastic being produced each year—much of it derived from fossil fuels—continues to grow. Virgin plastic is often cheaper to manufacture than recycled plastic, thanks to subsidies for oil and gas feedstocks. Without direct limits on new production, any progress on waste reduction will be undermined by the continued expansion of the plastic industry. Trade rules, many argue, are the only mechanism powerful enough to impose such limits on a global scale.
This debate is at the heart of the current negotiations for a Global Plastics Treaty. Oil-producing nations and the plastics industry have pushed for a narrow focus on waste management, arguing that better recycling is the path forward. But a growing coalition of countries and environmental groups insists on tackling the issue at its source—by setting legally binding caps on virgin plastic production. Proposed trade measures include penalties or border adjustment taxes on countries or products that exceed their production quotas, creating real economic consequences for failing to curb new plastic output.
The outcome of these negotiations will determine whether trade remains part of the plastic problem or becomes its solution. Global commerce has long enabled the plastic crisis, allowing waste and pollution to flow across borders unchecked. But with coordinated trade measures, that same system could drive a rapid shift toward circular economies worldwide. The success of the Global Plastics Treaty will hinge on whether nations are willing to embrace that transformation—and rewrite the rules of trade for a cleaner, more sustainable future.
